Kate’s professional trajectory is the byproduct of strong business acumen and a dedicated passion for the industry. From homeowner to landlord to agent to managing broker, her independent achievements and drive fuel her continuing success.
Originally from Milwaukee, WI, Kate spent time in Washington, DC before settling in Chicago. She has a degree in business management from American University and over a decade of business management experience.
As an agent, Kate used her relationship-building skills and passion for educating her clients to successfully navigate the housing market. Now, she uses those same skills to train and support both new and experienced agents. She is committed to their growth and her adaptable leadership style allows her to meet her agents where they are and help them achieve their version of success.
In her free time, Kate is an avid baker and reader. She enjoys spending time outside with her dog, both in summer and winter, and loves exploring the beautiful city of Chicago.
In my 32 years of real estate, Kate O'Neill has been by far the best managing broker I've ever had. I have to say that I could not have landed in a better office. Kate helps me dream bigger than I would normally dream for myself. She's intuitive, she's thoughtful, she's quick to come up with a solution. Kate is very good with training, teaching, being there for people, encouraging the ag...
Kate O'Neill is my Managing Broker and I would say that in the last 11 years of me doing this, she has been one of the best Managing Brokers that I've gotten to share this experience with. She brings a different light to the industry and a different version of functionality and humanity that often gets lost in translation. I'm a big proponent of fair housing and Kate and I have had sever...
My husband, Mike McCallum, and I are the McCallum Homes Team at Baird & Warner North Center and Kate O'Neill is our managing broker. We rely on Kate for so many things - big and small, day to day. We didn't realize how much we really, really value having a non-compete managing broker to help us with our business and brand. One project that Kate recently did for me is that she went throug...
I figure I know how to navigate a deal every which way as a top performing Real Estate Broker, but if I get stuck, Kate supplies a brilliant alternative I had not thought of! I trust Kate to help me navigate this extraordinarily competitive 2026 market toward success, thanks Kate!
Kate is my Managing Broker and she's been wonderful to work with. I appreciate her swift response time to any kind of question I have. It doesn't matter if it's a text on a Saturday night or a Sunday morning, she always gets back to me. If she doesn't know the answer, she always finds that answer for me. It's been super helpful. Another thing I like about her is when I have a stressful s...

Kate was a wonderful realtor to work with! She was both determined and patient during our search for our first home.

Kate was extremely helpful and informative while helping us find an apartment. She was flexible with setting up visits and finding different properties to fit our needs. I would highly recommend Kate to anyone looking for an apartment or house!
Kate was an exceptional help to find our place. Not only did she go above and beyond finding us several places but every place fit our specific needs. Always on time and would take us on tours whenever we would ask. Would 100% go with her again when I take on my next move.
I highly recommend Kate! Her attention to detail, communication, and professionalism was on full display. Anytime I had a question or concern she was always there to help ease my concerns. I can't wait to work with her on all my future real estate endeavors.
Kate worked closely with me to find apartments in Chicago - she was always professional and truly exceeded my expectations as a realtor.

Kate was very helpful and found us a great place that we love!
Kate helped us find our apartment and made the entire process super easy for us. She was always quick and available if we had questions or wanted to schedule a tour, and knew exactly what we wanted and helped guide us based on that. I’d definitely go to Kate again next time we have to search!
We met Kate during our search. Upon running into her at a second open house, we agreed that Kate was the best agent to help us purchase our next place. Long story short, Kate did just that. Kate made the entire process seemingly simple and painless. We couldn't have asked for better counsel during the buying process. We highly recommend Kate!
